Patent GB-272257-A (GB)
Abstract: 272,257. Walter, H.,. and Broadwood, R. L. Dec. 14, 1925. Sparking-plugs. - A condenser is placed in shunt with the terminals of an electromagnetically-actuated sparking plug. As shown in Fig. 1, the core d<1> enclosed within the coil d passes through an opening in the wall of the plug into proximity with the blade f, which carries a platinum contact f<1>. The condenser g is connected to the insulated terminal and the plug casing. In a modification the solenoid is mounted within a cover attached to the plug casing and is supported on the casing by a bracket. Passing axially through the casing is a spindle to which is secured at the one end an arm forming the armature of the solenoid and at the other end, within the combustion chamber, an arm the end of which makes contact with the end of an insulated wire or rod also passing through the casing and connected to one end of the solenoid coil. The condenser is mounted on the supporting bracket adjoining the solenoid. In a second modification the condenser, coil, and armature form concentric cylinders, the axes of which are coincident with the axis of the plug. The action of the coil is to cause the armature to slide against spring action and strike the end of a central rod. The opposite end of this rod and the inner surface of a ring screwed into the plug casing constitute sparking terminals. In a fourth form or blade projecting transversely from the casing wall carries the armature of the solenoid core, which is again coaxial with the plug. From the underside of the armature depends a rod carrying one of the sparking terminals. This terminal is of platinum and projects from a conical member which screws on to the depending rod, an enlarged portion of the terminal being clamped within a recess between the clamping member and rod. In a further' modification, Fig. 6, the coil d and condenser g are mounted on opposite sides of a tubular member t<2> secured to the member e carrying one terminal e<1> and threaded to engage the engine cylinder. The second terminal f<1> forms the reduced extremity of a rod f oscillated by the armature v of the electromagnet. The reduced upper end f<2> is supported in a plug t<3> screwed within the tubular member t<2>. A choke coil c, Fig. 1, may be connected in circuit between the plug and the source of current.

Abstract: 810,811. Wrapping-machines. BATE, F. D. Jan. 28, 1957 [Oct. 26, 1955], No. 27342/55. Class 94(1). A semi-automatic wrapping machine comprises a receptacle or former 42 which is reciprocably mounted for movement towards and away from a support 22 under the action of mechanism operated by cams on driven shafts 24, 25, the article and wrapper being inserted by the operator into the receptacle when the latter is in its upper position, the receptacle then being lowered to a position at which various folding and sealing operations are effected and finally being returned to its upper position where the wrapped article is ejected on to a delivery belt 102. A web of wrapping material is fed by rollers 108, 113 from a roll on a spindle 116 and severed by a cam-operated knife 119 to form a wrapper which is deposited on a grid 115. The operator locates the wrapper between V-shaped guides 136 on a plate 130 which is slidable in guides 134 on the machine cover 23, places an article, e.g. a Swiss roll, centrally on the wrapper and then inserts the article and wrapper through a large opening in the plate into the receptacle 42 so that the wrapper is folded about the article in the form of a U. The plate 130 is then pulled downwardly against the action of springs 133 until it is locked in a lowered position by the engagement of a pin 137 with the hooked end 138 of a lever 139. During this movement, an abutment 140 on the plate operates a switch 141 to start the driving motor and the cam shafts 24, 25 commence to rotate. As the receptacle 42 is lowered, folding members 46, 47, adjustably mounted on the support 22, make the first end tucks as shown in Fig. 6, and when the receptacle reaches its lowermost position the upstanding limbs of the U are folded over in succession, as shown in Figs. 7 and 8, by members 63, 68 and rollers 62, 65 on spring loaded arms 61 carried by cam-operated arms 50, 51, the roller 65 being heated to effect sealing of the longitudinal seam thus formed. The lateral end folds are then made by four plates 83, Fig. 10, which are rotatably mounted in the support 22 and oscillated by a cam-operated arm and chain and sprocket gearing, and as the receptacle 42 commences to rise, the final end folds are made by heated rollers 93, Fig. 11, on cam-operated arms 91. During the folding operations a further supply of wrapping material is fed by the rollers 108, 113 and severed by the knife 119, the latter striking the end of the lever 139 as it moves downwardly to release the lock 137, 138 so that the plate 130 is returned to its initial position by the springs 133 and the abutment 140 operates the switch 141 to stop the motor. The shape of the receptacle may be modified to suit articles of various shapes, such as sausages or stacks of biscuits,

Abstract: 240,114. Hazeltine Corporation, (Assignees of Wheeler, H. A.). Sept. 22, 1924, [Convention date]. Thermionic amplifiers and generators; receiving sets, construction of. - Undesired capacity reaction between two associated circuits, more particularly the input and output circuits of a thermionic valve or power amplifier when coupled through the internal electrode capacities, is neutralized by means of capacity elements only, the selected and fortuitous capacities being arranged in the form of a balanced bridge as shown in Fig. 1, where A, B represent the associated circuits and C<1>, C<11>, C1, C2 the balanced capacities. In Fig. 2, A represents the input and B the output of a valve amplifier, the capacity C' corresponding to the inherent interelectrode and similar undesired capacity, whilst the remaining capacities are circuit condensers. In Fig. 3 the balanced bridge is arranged in the output circuit, a choke coil 4 passing the directcurrent component, whilst blocking the highfrequency current. Fig. 7 shows the fundamental system of Fig. 1 extended to a third circuit D by the addition of a four-arm bridge C<b>, C<a>, C<d>, C<c> which acts as a pure capacity in the C1 arm of the main bridge in shunt to the capacity C0. The schematic arrangements of Figs. 1 and 7 are described in detail in the Specification as applied to single and multi-stage valve amplification both on the high and low frequency side of wireless reception comprising either tuned or untuned intervalve couplings. Fig. 9 shows the layout of the components of a set having two high-frequency stages and a detector, the input coupling coil 32 and the intervalve coupling coils 33, 34 being placed with their centres on the same straight line and their axes inclined at an angle of 55 in order to avoid magnetic coupling: or suitable magnetic screening can be employed for this purpose. The ratio of the capacity C2 to C1, Fig. 2, should preferably be considerably greater than unity, whilst that of C<1> to C, should be as small as possible, the value one-sixth being stated to be satisfactory. The balance secured by the capacity bridge arrangement is effective in preventing undesired reaction irrespective of the particular frequencies involved.

Title: Improvements in wrapping machinery
IPC: B65B25/00
Filed: 1945-10-19
Abstract: 603,378. Wrapping machines. ROSE, A. G., GILBERT, J. A., and ROSE BROS (GAINSBOROUGH), Ltd. Oct. 19, 1945, No. 27486. [Class 94(i)] A wrapping-machine of the kind in which the articles to be wrapped' are fed in succession to a series of pockets, each previously supplied with a wrapping, contained in a pocket member adapted to carry the articles in turn to a series of operating stations, comprises a mechanism to detect failure of the article-feeding mechanism to feed an article to any pocket and controlling an ejector adapted on such detection to pass through the base of the pocket containing no article as that pocket arrives at a pressing station, so as to eject the faulty package into an auxiliary magazine constituted by a hollow pressing member, at the same time as the pressing operation takes place. The invention is described as applied to a razor blade wrapping-machine generally similar to that described in Specification 593,368. A hollow rectangular pressing member 13 is adapted to descend on to each pocket 12 of the pocket member 11 as that pocket comes to rest at the pressing station, in order to press the flaps of the wrapper on to the blade, being carried on a bracket 14 which reciprocates vertically in a slide member 16 by link and lever mechanism 19, 21, 22 operated by a cam 25 on a shaft 26. The shaft 26 carries a second cam 39 which by link and lever mechanism 37, 36, 34 reciprocates vertically in a slide member 32, an ejector 31 adapted to pass through apertures 41 in the pocket 12. Each time a blade is delivered to a pocket 12 at the blade-feeding station, detecting mechanism as described in Specification 593,368 energizes a solenoid 48 to cause a stop member 43 to engage an extension 49 of the arm 37 to prevent the arm following the cam 39 under the influence of a spring 51, so that the ejector 31 does not operate. On failure to feed a blade to a pocket, the solenoid is not energized and the ejector forces the faulty package into the interior of the pressing member 13, the entrance to which is smaller than the packages so as to retain it effectively. The operation of the mechanism 48, 43 is described in detail in Specification 593,368 with reference to Figs. 4 and 5 of the drawings accompanying that Specification, and is arranged so that the ejection takes place when the faulty package has reached the pressing station. The Provisional Specification describes the wrapping machine as comprising a pocket wheel with six pockets each brought in turn to rest at six stations, at which (1) a wrapper blank is fed to the pocket and gum applied to it, (2) a liner blank is formed and placed over the wrapper, (3) the blade is deposited on the liner (4) the flaps of the wrapper and liner are folded over the blade, (5) the pressing operation takes place, together with the ejection of faulty packages as already described and (6) the completed packages are delivered into a magazine.
